Visible-light-induced tandem ring opening/1,6-conjugate addition of cyclobutanols with p-quinone methides under metal- and additive-free We report, for the first time, a visible-light-promoted tandem ring opening/1,6-conjugate addition of cyclobutanols with p-quinone methides. This transformation proceeded smoothly in the presence of organic photocatalyst [Mes-Acr-Me]+BF4-, affording a series of δ,δ-diaryl ketones in moderate to excellent yields.
